Surah Hud (Hud), Verse 7

وَهُوَ الَّذِیْ خَلَقَ السَّمٰوٰتِ وَالْاَرْضَ فِیْ سِتَّةِ اَیَّامٍ وَّكَانَ عَرْشُهٗ عَلَی الْمَآءِ لِیَبْلُوَكُمْ اَیُّكُمْ اَحْسَنُ عَمَلًا وَلَىِٕنْ قُلْتَ اِنَّكُمْ مَّبْعُوْثُوْنَ مِنْ بَعْدِ الْمَوْتِ لَیَقُوْلَنَّ الَّذِیْنَ كَفَرُوْۤا اِنْ هٰذَاۤ اِلَّا سِحْرٌ مُّبِیْنٌ ۟

“He it is Who created the heavens and the earth in six Days - and His Throne was over the waters - that He might try you, which of you is best in conduct. But if thou wert to say to them, "Ye shall indeed be raised up after death", the Unbelievers would be sure to say, "This is nothing but obvious sorcery!"”
